Hybrid Approach for Face Recognition from a Single Sample per Person by Combining VLC and GOM

Journal of Intelligent Systems, 2019
This paper proposes a new face recognition system based on combining two feature extraction techniques: the Vander Lugt correlator (VLC) and Gabor ordinal measures (GOM). The proposed system relies on the execution speed of VLC and the robustness of GOM.

Navigating challenges in prosthodontic rehabilitation after long‐term delay following fibula free flap reconstruction with a unique overlay removable prosthesis and large vertical dimension increase

Journal of Prosthodontics, EarlyView.
Abstract This case report highlights the experience of one maxillofacial surgical patient who delayed prosthodontic treatment for 7 years as they saved to self‐fund access to a subsidized prosthodontic service. Without the benefit of a restored opposing dentition for a prolonged period of time, maxillary occlusal plane disruption occurred as a ...
